[Endometrioid ovarian neoplasms with epidermoid structures].

Under study was the intraoperative material from 32 patients with endometrial ovarian neoplasms having an epidermoid structure. Epidermoid foci were found to be pathognomonic only for the endometrioid epithelium. This fact may be used for the differential diagnosis with serous neoplasms. Biologically adenoacanthomas may be qualified as borderline processes, i.e. potentially a low grade of malignancy.
